Anchor Watch
Anchor watch monitors the position of an anchored vessel and ensures there is no drift by keeping the vessel within a safety radius.

→ Anchoring
When approaching the anchoring point, press 
1. Enter the safety radius
Enter the Radius of safety circle.
Attention
Safety radius is calculated in advance by the navigating officer.
2. Activate anchor watch
At the point of letting go the anchor, press Activate.
Hint
The anchor is let go while the vessel has sternway. Activating anchor watch fixes the anchor dropping point.
When anchor watch is activated, the anchor watch button shows: Anchor watch on.
Hint
As the vessel weighs on the anchor chain and moves astern, the monitoring sector will be oriented along the course vector, in the direction of the stern.
Chart display
The chart will display the set safety circle and the anchor symbol at the anchor dropping point.
The safety zone is bounded by an orange circle.
Hint
The vessel is within the safety radius.
Drift monitoring
When the vessel outline exceeds the safety radius, the circle and the anchor symbol will turn red, and a Warning (Anchor watch) will be generated.
Important
If the warning is not acknowledged by the navigating officer within 2 minutes, and the vessel outline exceeds the safety radius, the warning escalates to an Alarm.
Danger
A tendency of the vessel to move beyond the safety radius may indicate that the anchor is dragging, and the navigating officer must take all measures to prevent the development of an emergency situation.
Return to the safety zone
If the vessel outline returns within the safety circle, the warning/alarm becomes inactive.
When anchor watch monitoring is disabled, all warnings are cleared.
Tip
It is recommended to calculate the safety radius in accordance with the methods and recommendations adopted for the given vessel. This manual does not contain any recommendations on calculating anchor chain length or the safety radius.
